Let me propose a less disruptive change.

I think the only name that V4 should not use is channel access.
Thus the name channel is OK.

http://www.thefreedictionary.com/channel

Has the definition:

1. The bed of a stream or river.
...
6. A course or pathway through which information is transmitted: new 
channels of thought; a reliable channel of information.
7. A route of communication or access. Often used in the plural: took 
her request through official channels.
...

Both channel access and pvAccess satisfy 6) or 7).
If this is accepted the only name in pvAccess that needs to change is 
ChannelAccess.
In Java this is an interface.
In C++ it is a class.
In addition the documentation (many places) must be checked to see that 
channel access is only used to
talk about what comes with epics base.

We could rename ChannelAccess with minimal change to code and Documentation.
Changing the name Channel affects LOTS and LOTS of code and documentation.

I also suggest that the  name ChannelAccess be replaced by PVAccess.
